A PDF and an HTML version is included in the PHPBee download, however you can still read the manual online here or download it in separate packages.

• Read the manual online [this will be available here in a week]
• Download PDF version of manual
• Download compressed HTML version of the manual

The code is also rich in API documentation comments (using the phpdoc standard), so you can extract the actual API documentation, or read it while you look at the source code.

Slides

We also have the slides from the International PHP Conference 2002 about rich clients and documentation. You may also be interested in these areas.
